Water is the enemy of any home foundation. When planning a landscaping project, many homeowners focus on the look of the stone but overlook the engineering required to manage rainwater and snowmelt. Improper drainage can lead to flooded basements, eroded landscapes, and shifted pavers.
Positive Grading
The golden rule of hardscaping is ensuring a “positive grade” away from the house structure. We typically aim for a 1% to 2% slope, roughly a quarter inch per foot, away from the foundation. This ensures water naturally flows toward lawns or catch basins rather than pooling against your basement walls.
During restoration projects, we often find that old patios have settled backwards over time, funneling water toward the house. Correcting this slope is always the first priority.
Common Drainage Solutions
French drains: a trench filled with clean gravel and a perforated pipe wrapped in fabric. It captures surface and groundwater and redirects it to a safe discharge point. Ideal for soggy lawns or areas where water tends to collect.
Channel drains: sleek, linear drains installed directly into the patio or driveway surface, often in front of garage doors or at the bottom of sloped walkways. They capture sheet flow and pipe it away before it enters your garage.
Permeable pavers: an eco-friendly option gaining popularity. These systems allow water to pass through the joints between stones into a specialized aggregate base below, where it can infiltrate the soil naturally.
Protecting Your Investment
Effective drainage extends the life of your hardscape. Water that pools on pavers can seep into the base, freeze, and cause heaving. By prioritizing drainage in the design phase, we help keep your landscape stable and dry for decades.
